Rail-clamp Chocks Patents (Class 104/258)
  • Patent number: 9718649
    Abstract: A lifting and support device comprises a first yoke having a first support arm that defining a first wedge slot above the first support arm and a second yoke pivotally coupled to the first yoke having a second support arm inwardly extending toward and laterally spaced from the first support arm and defining a second wedge slot above the second support arm. The first and second wedge slots are substantially aligned when the first and second yokes are in a closed position. A wedge is configured for insertion within the first and second wedge slots when the first and second wedge slots are substantially aligned to hold a structure between the wedge and the first and second support arms of the first and second yokes in order to support a structure relative to the lifting and support device.

  • Patent number: 8485105
    Abstract: Devices and systems for stopping travel of a railcar along rails is provided, the railcar having wheel treads that ride on the rails. A railcar stop is configured to engage at least one wheel tread of the railcar to stop travel of the railcar along the rails. The railcar stop extends above the rails at a first height prior to engagement with a wheel tread and extends above the rails at a second, greater height after engagement with the wheel tread.

  • Patent number: 8485107
    Abstract: A device and system for controlling travel of a railcar along a set of rails is provided. In one example, a railcar stop is coupled to the set of rails and is selectively movable between a first position wherein the railcar is free to travel along the set of rails and a second position wherein the railcar stop engages the treads of the wheels to thereby prevent travel of the railcar in at least one direction along the rails.

  • Patent number: 6216601
    Abstract: Apparatus for limiting a travel path of running gears, in particular hoists, traveling along a running rail of a type having at least one flange and a web, includes a pair of side elements which are securable to opposite sides of the flange and provided with at least one buffer, and a clamping unit in the form of a tie element, for bracing the side elements together and pressing the side elements against the sides of the flange.

  • Patent number: 6155178
    Abstract: A wheel stop for an overhead rail vehicle includes a wheel block assembly pivotably fastened to a clamping assembly. The wheel block assembly is provided with an actuator connector positioned such that a downward force on the wheel block assembly tends to move the wheel block assembly from a wheel-engaging position to a retracted position. An actuating assembly permits an operator to actuate a lift rod for moving the wheel block assembly from a ground location. Shock absorbing elements on the wheel stop prevent damage. The actuating assembly is provided with apertures for receiving a padlock to prevent tampering.

  • Patent number: 6152042
    Abstract: A railcar retarder assembly for use in a railroad trackwork such as a railcar classification yard is provided with a fixed base plate, a vertically-oriented pivot shaft secured to the base plate, an elongated and curved cam member mounted on the pivot shaft, and a horizontally-oriented hydraulic subsystem piston element that induces reaction hydraulic damping forces which are transmitted horizontally to the wheel flanges of a passing railcar to thereby reduce the rolling velocity of the railcar.

  • Patent number: 5865122
    Abstract: A shoe or clamp assembly for securing a buffer stop or bumping post to railroad track with a predetermined magnitude of retardation against sliding movement of the buffer stop when the same is engaged by a moving railcar to be stopped. The shoe assembly which clamps against opposite sides of a buffer stop wall, and also clamps against opposite sides of a rail, is secured by at least one bolt and nut and also a spring stack so that a torque wrench is not required in order to effect such securement.

  • Patent number: 5836252
    Abstract: The invention relates to a rail brake element, in particular for use in rail brake buffer blocks, comprising a pair of clamping plates extending about a rail head from each side and supported against its top surface, which clamping plates are clamped against the rail head by a clamping device including a clamping bolt and a spring assembly, and include at its portion below the rail head a brake lining portion of suitable rigid friction material for engagement with the rail head, wherein the brake lining layer engages the rail head by means of a raised portion of wear material having a static friction coefficient smaller than that of the brake lining layer.

  • Patent number: 4535701
    Abstract: The device comprises a body (1) for placing on a rail (R) for the purpose of receiving a wheel of a machine to be slowed down and stopped and forming an abutment for the wheel, and an arrangement for connecting the device to the rail. The connecting arrangement comprises a plate (7) carrying elastically yieldable claws (10 and 11) which are maintained spread apart in their position of rest. The plate (7) is adapted to be applied against the rail (R) and is pivotally connected to an arrangement (21) for moving the claws (10 and 11) towards each other for the purpose of closing them around the head of the rail. The arrangement (21) is connected to the body (1) of the device.

  • Patent number: 4216724
    Abstract: A device for stopping a wheeled vehicle which runs on a guide rail, comprises a scotch block connected to the rail, against which the front wheel of the vehicle can strike. The scotch block in this position fits a part of the outer circumference of the wheel up a certain height. The scotch block is formed by two distinct parts, namely a lower part and an upper part, the lower part being fixed rigidly to the rail and the upper part being retractable from a high position to a low position and vice-versa by rotation about an axis. Movement from the low position to the high position is controlled by an operating component situated upstream from and immediately adjacent the lower part of the scotch block, which component is actuated by a front wheel of the vehicle.
